Energy & heavy industry Stainless steel for pulp & paper

To produce something as simple as a sheet of paper, complex equipment is required – and all of it functions within corrosive environments. With long service life and low life-cycle cost, stainless steel is the obvious choice for this industry.

Outokumpu has been building partnerships with the world’s leading pulp and paper producers for nearly a century. Our expertise in this segment is built on a solid foundation of industry experience. We have an exceptional track record in supplying materials, expertise and support to build reliable, safe and more cost-efficient plants.

Our high-strength duplex stainless steel grades have become an especially popular choice for a wide range of applications. Nearly all pressure vessels used in pulp and paper today are made of duplex stainless steel. Duplex is also increasingly used in non-pressurized vessels and main process equipment.
